2 GHX-10 Overview
2.1 GHX-10 Description
The GHX-10 is a Universal Cross Converter that incorporates High-Definition Multimedia
Interface technology, and SDI connectors that allow for any input to be converted to any output
format or scan rate. It supports both SD and HD video and employs high quality 12 bit bi-cubic
interpolation to ensure the highest quality picture. The GHX-10 can tackle many conversion
tasks. It can be used as a computer DVI to HD-SDI converter (using a DVI to HDMI® adapter
cable), HDMI resolution converter, or as an HD video up-converter or down-converter. It
supports up to 8 channels of AES, HDMI and SDI audio. A two lines LCD display and scroll
wheel simplify navigation through the GHX-10's menus.
2.1.1 GHX-10 Front Panel
This is a snap shot of the front panel:
Menu Wheel Signal LEDs
SD Card
An LCD screen is available in the middle of the front panel to facilitate controlling the GHX-10
without using the On Screen Display.
The scroll wheel with built in Select button and the ESC button can be used to navigate the
menu structure and setup the unit.
The four LED indicators reflect the status of the various input signals:
• SDI-A LED
• SDI-B LED
• HDMI LED
• SYNC LED
The “PWR” LED lights up when the GHX-10 is powered ON.
The infra-red sensor can be used to remotely control of the GHX-10, see Section 4.
A SD Memory connector is available and can be used to perform firmware update.

3 GHX-10 Front Panel Controller
Throughout this chapter “press Select” refers to pressing the front panel scroll wheel button of
the GHX-10 – see Figure 1.
3.1 Menu Items Overview
Press “Select” to enter the GHX-10 menu system then turn the “Wheel” to access the different
menus:
• Input
• Output
• Image
• Sync
• Audio
• OSD
• System
• Status
Press “Select” to navigate one of the above menu items and access the list of available submenus. Browse the list of available sub-menus by turning the “Wheel”, then press “Select” to
change settings of a given sub-menu.
Browse the available values by turning the “Wheel”. To choose the desired value, press
“Select”. The selected value should be flagged with the # sign on its right which is the current
setting indicator.
To go back to a higher level in this menu tree, press on the “ESC” button – Keep pressing it to
exit the menu system.
The following tables list all GHX-10 setup parameters, items in bold are factory defaults. All
video formats show frame rates and not the field rates, so 1080i-60 fields per second will be
shown as 1080i-30 frames per second.

3.3.1 Color Space
The ITU-R BT.709-5 (HD formats) and ITU-R BT.601-5 (SD formats) Standards define the
range of color values in a digital signal to be:
• 16 to 240 for 8bit coding
• 64 to 960 for 10bit coding
The GHX-10 color space conversion supports these standards, but it also supports full range by
allowing the color values to be between:
• 0 to 255 for 8bit coding
• 0 to 1023 for 10bit coding
On the GHX-10 the full range modes are designated by the “ext” following the color space
conversion mode.

• If the output interface is set to SDI and if the selected output format is a valid HDMI
resolution, both SDI and HDMI outputs will be active with proper colors on both outputs.
This is due to the presence of a dedicated color space converter on the HDMI output.
• If the output interface is set to DVI (HDMI) and if the selected output format is a valid SDI
resolution, both HDMI and SDI outputs will be active but the SDI output colors might be
wrong. This is due to the presence of a dedicated color space converter on the SDI
output (this might change in future releases).
